New microcontrollers optimised for consumer and industrial applications

Toshiba Electronics Europe GmbH offers 21 new microcontrollers in the M3H group as new products in the TXZ+ Family Advanced Class, manufactured in a 40nm process. The group includes an ARM Cortex-M3 core running at speeds up to 120MHz, integrated 512kB (max.) code flash, and 32kB data flash memory with 100k write cycle endurance and 64kB of RAM. These microcontrollers also provide assorted interface and motor control options, such as an encoder and programmable motor driver. As a result, the group devices are ideal for various applications, including motors, home appliances, and industrial equipment.

In response to consumer and industrial equipment diversity, the new group products have enhanced communications functions integrated as UART, TSPI, I2C, and a two-unit DMAC. Furthermore, a digital LCD driver is included to lower the number of components for display function, aa contrast adjustment, and ensure a flexible board layout.

These devices support various sensing applications with a high-speed, high-precision 12-bit ADC that lets individual sample and hold times to be set for each of the 12 to 21 ADC input channels Also, they offer a solution ideal for controlling AC motors and brushless DC motors together with an on-chip A-PMD circuit that can function synchronously with the 12-bit analog/digital converter.

Also included within the highly integrated device is a dual-channel, 8-bit DAC and up to 135 dedicated I/O ports. Other peripherals include a RMC and CRC calculation circuit.

The self-diagnosis functions contained in the devices for ROM, RAM, ADC and Clock assist customers to achieve IEC60730 Class B functional safety certification.

The new microcontrollers operate from a voltage of 2.7V to 5.5V DC and are housed in high-density 64 to 144 pin LQFP packages.
